I was wondering if someone could tell me how I can improve my thesis statement/opening paragraph. I'm writing an essay on hamlet from the perspective of formalism (examining a work of literature's language and structure). Here it is:

Formalism is a type of literary criticism which examines the structure of the literary work, analyzes the use of language, disregard issues external to the play, and hold the work of literature as an art form in itself. In Hamlet, Prince Hamlet reveals his true thoughts, feelings, motivation, and overall state of mind through his seven soliloquies and numerous puns.
